The author of the [clock] changes should answer in the next few days
about the precise rationale, but until then, note the new [clock add]
command that's the recommended way to do things like above with Tcl 8.5.
% clock format [clock seconds]
Mon Aug 29 14:43:08 -0400 2005
% clock format [clock add [clock seconds] +1 day]
Tue Aug 30 14:43:27 -0400 2005
% clock format [clock add [clock seconds] -1 day]
Sun Aug 28 14:43:43 -0400 2005
% clock format [clock add [clock seconds] +0 day]
Mon Aug 29 14:43:55 -0400 2005
[clock add] understands subtleties like how adding "1 day" is different
from adding "24 hours".
